2015-12-16  In gold ores, pyrite and arsenopyrite often occur in three morphological types: coarse, porous (blastic) and fine-grained. Framboidal and microcrystalline pyrite are also observed in some gold deposits. Generally, the order of concentration of gold in pyrite and arsenopyrite is: fine-grained>porous>coarse-grained (Figures 8 9). In some
